A wheel hub has inboard and outboard bearings separated by a spacer. A cap is located on an outboard surface of the hub to hold the outboard bearing in place. The cap may be held in place by a cap retainer and may be press fit into the bore. At least one alignment element may be used to substantially align the spacer with the inboard and outboard bearing assemblies during installation of the wheel hub onto an axle.
